Board design
We propose the optimum design based on reliability and achievements.
High difficulty from single-sided boards to high-multilayer boards and build-up boards
In addition to handling the board design in total, we also support transmission path and noise simulation verification.
High frequency board
High-frequency boards, where control of signal transmission speed and loss is of utmost importance, are required to form highly accurate signal wiring.
The material of the board to be used is selected in consideration of the loss due to the frequency used and the ease of handling of the board.
We also propose composite multilayer printed wiring boards (hybrid boards) from the viewpoint of unit miniaturization and cost reduction.
Power supply board
Pattern design is just as important as circuit design in power supply design.
Improper layout leads to increased noise, poor regulation and lack of stability. However, to put it the other way around, it means that noise can be suppressed by arranging and wiring with careful consideration of them. We have abundant designers who also design power supply boards.
Double-sided to high-multilayer board
We have many achievements from double-sided boards to high-density and high-multilayer boards.
Our motto is to understand the characteristics of parts and to design with consideration for board manufacturing and mounting after design. We often hear from customers who request us that the response and response during design is good.

We try to design with EMI in mind.
It is also possible to perform electromagnetic field simulation analysis and surface resonance analysis during the artwork or before manufacturing.
We also support pre-simulation such as SI.
Example of pre-simulation [DDR3]
Wiring work can be started after pre-simulating SI, and various analyzes can be performed from CAD data.
